Best ContactOut Alternatives in 2026: 12 Tools for Sales Prospecting and Recruiting

Best ContactOut Alternatives: A cream contact-finder tool roll unfolds to show a candidate file, a sales envelope rack and a bulk enrichment funnel.

Turn this article into takeaways for your work.

Each assistant summarizes the article only for you and suggests best practices for your work.

If you outgrew ContactOut's single paid seat, Lusha, SignalHire and Apollo are the first three to test: Lusha for plan-based simplicity with seats bundled, SignalHire for unlimited users and charges only on a hit, Apollo for a big database plus sequencing. Recruiters who still want a LinkedIn sidebar should add Kaspr (its Business plan includes Recruiter Lite) and FullEnrich, which charges 3 credits for a personal email. Teams that want a compliance-first sales database should look at Cognism, and enterprise buyers at ZoomInfo.

We compared 12 tools on four things that decide whether a contact finder pays for itself: how credits are metered, what the vendor claims about accuracy, who the seat model suits, and what compliance exposure you inherit. Prices below are the vendors' own figures with their billing terms. Where a vendor doesn't publish a price, we say so and label any outside figure as reported.

This page is about replacing ContactOut. If you want the whole category of LinkedIn-based finders ranked side by side, read the best LinkedIn contact finder tools. For the wider market, start at the best sales intelligence tools in 2026.

Key Facts

Why Teams Look Past ContactOut

ContactOut is a good product, and it earns its popularity. It says it's trusted by 1.4M recruiters and sales reps, it works as a browser extension on LinkedIn profiles, and it surfaces personal emails that a work-email database often misses. It also lists native ATS and CRM integrations and an API. That mix is why recruiters adopted it first and sales teams followed.

ContactOut Seat and Export Limits: A cream single-key access slot stands before a stack of blank contact cards with an adjustable export gate.

The reasons people move on are mostly about shape, not quality. Here's what the vendor's own pages say.

Pressure point What ContactOut's pages say Why it pushes people to look elsewhere
Seats Paid plans carry a "1 user per company limit" A team of five reps or three recruiters can't share one paid plan
Export caps Email plan: 300 exports a month or 3,600 a year. Email + Phone: 600 a month or 7,200 a year Heavy sourcing weeks hit the ceiling fast
"Unlimited" Fair use of 2,000 email and 1,000 phone credits per account per month Unlimited reveals still have a cap in the terms
Phones Email plan has no phones; phones need the higher plan Sales reps who dial pay for the second tier
Price display Email $49/mo billed monthly (list shown as $99); Email + Phone $99/mo billed monthly (list shown as $199) Struck-through list prices make budgeting harder; plan on the billed figure
Data claims The data page says 800M profiles; the pricing page says 700M+ Headline database numbers don't reconcile, so test with your own list
Personal emails A core selling point Private addresses carry a higher consent bar in the EU and UK

None of that makes ContactOut wrong for you. If you're a solo recruiter who works from LinkedIn all day, the single seat is no problem. The pain starts when a second or third person needs access, when you want one credit pool across a team, or when your legal team asks where the emails come from.

ContactOut's pricing, stated exactly

Plan Billed monthly Billed annually Export allowance Notes
Free $0 n/a 5 emails, 5 phones, 5 exports per day 1 user per company
Email $49/mo $468/yr 300/mo or 3,600/yr Unlimited emails (fair use), no phones
Email + Phone $99/mo $948/yr 600/mo or 7,200/yr Unlimited emails and phones (fair use)

Source: ContactOut pricing. Team and API access is "Contact us", and the site advertises unlimited sales users for $299 without stating the billing term, so confirm that one with the vendor. The data page claims 150M personal emails, 200M work emails and 100M direct dials, with "99% accuracy", and states CCPA, GDPR and SOC 2.

Recruiters vs Sales: Which Alternative Fits Which Job

ContactOut sits in the middle, which is why replacing it is awkward. The two audiences use contact data differently.

Recruiting vs Sales: What's the Difference?: A paired wide illustration with a clean empty center gutter: left, a cream candidate dossier with a personal envelope feeds an ATS filing cabinet; right, a cream company-account dossier feeds a work-envelope sequence rack and CRM tray.

Need Recruiter sourcing Sales prospecting
Typical target Individual candidates, often passive Decision makers at target accounts
Email type that works Personal addresses often matter Work emails first, personal as backup
Phone use Short calls to candidates Dialing in sequences, often with do-not-call checks
Where the data goes An ATS or a spreadsheet A CRM or sequencer
Volume pattern Bursty around an open role Steady daily and weekly lists
Tools worth testing Kaspr (Recruiter Lite), SignalHire, FullEnrich, RocketReach Lusha, Apollo, LeadIQ, Cognism, ZoomInfo

Vendors rarely publish recruiter-specific accuracy numbers, so the only fair test is your own: pull 50 real candidates or prospects, run them through two tools, and count what bounces.

1. Lusha: the plan-based default for small teams

Lusha is the closest swap for a rep who liked ContactOut's one-click reveal but needed a second seat. It's flat per plan, with seats bundled, not per user.

Lusha Bundled Seats: Two cream access passes sit clipped to one shared plan folder while a larger five-slot pass holder stands behind it.

Plan Monthly billing Annual billing Credits Seats
Free $0 n/a 40/mo 1
Starter $49.90/mo $37.45/mo ($449.10/yr) 400/mo or 4,800/yr 1
Pro $69.90/mo $52.45/mo ($629.10/yr) 600/mo or 7,200/yr 2 free seats
Premium $399.90/mo $299.95/mo ($3,599.10/yr) 3,400/mo or 40,800/yr 5 free seats
Scale Custom Custom Custom Custom

Source: Lusha pricing. Annual billing is 25% off. An email costs 1 credit and a phone number costs 5. Monthly plans roll unused credits over up to twice the monthly cap, while annual credits are issued upfront and reset at year end. Above five users you move to sales. Lusha claims 515M+ contacts, 98% email accuracy and 85% US and 86% global phone accuracy, plus GDPR (ePrivacyseal), CCPA (TrustArc), SOC 2 Type II and ISO 27701. The plan comparison includes a do-not-call row.

Pros Cons
2 or 5 seats bundled on Pro and Premium Phone credits cost 5 each
Monthly rollover up to 2x the cap Annual credits reset at year end
Stated phone accuracy and compliance badges Vendor claims, not independent tests

Best for: 2 to 10 person sales teams that want a ContactOut-style reveal with seats included.

Not ideal for: recruiters who depend on personal emails.

2. Apollo.io: data, sequencing and a free pool

Apollo is the broad pick. It says it holds 240M+ contacts and 30M+ companies with 98% email accuracy, then adds sequences, a dialer and a CRM-style workspace. If you're also weighing it against other engagement tools, see our Apollo alternatives guide.

Apollo Finder and Sequencer: A single cream workbench integrates three large functional objects: an envelope lookup lens, a sequence carousel and a phone receiver.

Plan Annual (per seat/mo) Monthly (per seat/mo) Credits
Free $0 $0 900/seat/yr, granted monthly (75/mo)
Basic $49 $65 30,000/seat/yr annual; 2,500/seat/mo monthly
Professional $79 $99 48,000/seat/yr annual; 4,000/seat/mo monthly
Organization $119, min 3 seats Annual only 72,000/seat/yr annual; 6,000/seat/mo

Source: Apollo pricing. Annual billing is 24% off. An email costs 1 credit and a phone number 8. Credits are pooled across the team and don't roll over, including add-on credits. "Unlimited" features sit under a fair use policy with no numeric cap published. The trial is 14 days with 75 credits, then you fall to the free plan. Apollo states GDPR compliance on a legitimate-interest basis, SOC 2 Type II and ISO 27001; its data page makes no CCPA or do-not-call statement.

Pros Cons
Finder, sequencer and dialer in one tool Per-seat pricing grows with the team
1-credit email, one pool for everything Credits don't roll over
Free plan to test Phone reveals cost 8 credits

Best for: sales teams that want to replace ContactOut and a sequencer with one login.

Not ideal for: recruiters who need an ATS-first workflow.

3. RocketReach: lookups, exports and an API

RocketReach is the better fit when contact data needs to flow into other systems. It claims 700 million professionals and 60 million companies with 98% accuracy, and the lookup is only charged if a verified email or phone is found.

RocketReach Export Metering: A cream contact sleeve passes through a large inspection hoop into a conveyor-free export drawer.

Plan Monthly billing Annual billing (US list) Monthly lookups
Free $0 (5 free lookups) n/a 5 total
Essentials $49/mo $399/yr 100
Pro $99/mo $899/yr 250
Ultimate $209/mo $1,699/yr 1,000

Source: RocketReach pricing. Annual prices differ by region, so these are the US list. Annual plans advertise unlimited lookups (Essentials email only, Pro and Ultimate email and phone) with a fair use cap of 10,000 lookups a month. Bulk lookups, API calls, CSV exports and CRM pushes consume exports, not lookups, at 1,200, 3,600 and 20,000 a year across the three tiers. Pricing is per seat. Custom team plans start at $6K a year. RocketReach lists SOC 2 Type II and ISO 27001.

Pros Cons
Refund when nothing is found Two meters (lookups and exports) confuse budgets
API and bulk support Annual price varies by region
Free account to test Per-seat model

Best for: teams moving contact data into a CRM or internal tool.

Not ideal for: a single recruiter who wants a simple sidebar.

4. SignalHire: unlimited users, charged only on a hit

SignalHire is the straightforward answer to ContactOut's one-seat rule. It says it doesn't charge per seat, and credits are shared across unlimited users. One credit unlocks one contact, charged only if at least one email or phone comes back.

SignalHire for Shared Sourcing: A broad cream communal sourcing ledger is held open by four distinct empty tool docks along its edge.

Plan Monthly billing Annual billing Credits
Free $0 n/a 5 credits, or 10/month with the browser extension installed
Emails $49/mo (600 credits) or $69/mo (1,000) $469/yr (7,200) or $689/yr (12,000) Email only
Phones and Emails & Phones $49/mo (300) or $69/mo (435) $469/yr (3,600) or $689/yr (5,400) Phones included
Unlimited (emails) $79/mo $63/mo billed annually Fair use
Unlimited (phones and emails) $99/mo $83/mo billed annually Fair use

Source: SignalHire pricing. Unlimited plans have a fair usage cap of 2,000 credits a month, per the pricing page. SignalHire claims 900M+ profiles but publishes no accuracy percentage. It states GDPR and CCPA compliance in its privacy FAQ, and the entity is SignalHire Sp. z o. o.

Pros Cons
Unlimited users on every plan No accuracy number to hold it to
Charged only when a contact is found Confirm rollover rules
Free tier with the extension Unlimited tops out at 2,000 credits a month

Best for: recruiting teams of 3 to 20 that share a credit pool.

Not ideal for: buyers who need a published accuracy figure.

5. Kaspr: LinkedIn extension with Recruiter Lite

Kaspr is the nearest functional twin to ContactOut: a LinkedIn extension for emails and phones. It's owned by Cognism, which bought 100% of Kaspr SAS in May 2022. It says it holds 200 million+ European B2B contacts from 120+ sources, re-validated every two months, with no accuracy percentage.

Kaspr Recruiter Lite Access: A cream browser-extension clip attaches to a candidate dossier and locks into a Business plan sleeve.

Plan Annual (per user/mo) Monthly (per user/mo) Allowance
Free EUR 0 EUR 0 15 B2B email, 5 phone, 5 direct email credits per month
Starter EUR 45 EUR 59 Unlimited B2B email, 100 phone/mo, 5 direct email/mo
Business EUR 79 EUR 99 Unlimited B2B email, 200 phone and 200 direct email/mo, Recruiter Lite
Organization Annual only, 5-user minimum n/a 24,000 phone and 24,000 direct email a year

Source: Kaspr pricing. USD list prices are $49 and $65 for Starter and $79 and $99 for Business. The vendor's own compare table shows a different free-tier credit count, so confirm the allowance in the app. Credits roll over on paid plans and are shared across users. "Unlimited" is capped at 10,000 credits per account per month.

The regulatory history matters for a ContactOut buyer, because both products work from LinkedIn profiles. The CNIL fined Kaspr EUR 240,000 for collecting contacts of LinkedIn members who had restricted their visibility, plus breaches of transparency, retention and access rules.

Pros Cons
Unlimited B2B email on paid plans CNIL fine for collection practices
Recruiter Lite on Business Phone credits are limited per month
Rollover and shared credits Same LinkedIn-extension risk profile

Best for: European recruiters and sellers who've done their own legal review.

Not ideal for: buyers who need a clean regulatory record.

6. LeadIQ: capture to CRM for SDR teams

LeadIQ captures prospects from LinkedIn into your CRM and sequencer. It claims 750 million+ professional profiles, an 85% global mobile match rate (70% in EMEA) and phone accuracy above 90%, and says every data supplier passes a GDPR and CCPA review.

Plan Monthly billing Annual billing Notes
Free $0 n/a 1 user, 50 credits
Pro, 200 credits/mo $20.00/mo $15.00/mo (25% off) 5 users included
Pro, 6,750 credits/mo $290.25/mo Discounted Top slider tier
Enterprise Contact us Annual only Custom

Source: LeadIQ pricing. An email costs 1 credit, a phone 10, email plus phone 11, and account enrichment 3. Confirm rollover rules with LeadIQ. Any plan has a 30-day free trial.

Pros Cons
5 users included on Pro Phone reveal costs 10 credits
Small entry price on the slider Confirm rollover rules
Built for capture-to-CRM flow Less suited to ATS use

Best for: SDR pods of 3 to 10 that live in a CRM.

Not ideal for: recruiters sourcing for open roles.

7. Hunter: the domain-first email finder

Hunter works from the company domain outward, not from a LinkedIn profile. It says it has 150M professional email addresses indexed from 650M public sources. It's built around email finding and verification, so phone-heavy teams will want something else.

Plan Monthly billing Annual billing Credits
Free $0 n/a 50/mo, 1 email account
Starter $49/mo $34/mo billed $408/yr 2,000/mo (24,000/yr)
Growth $149/mo $104/mo billed $1,248/yr 10,000/mo (120,000/yr)
Scale $299/mo $209/mo billed $2,508/yr 25,000/mo (300,000/yr)

Source: Hunter pricing. Plans are flat per account with unlimited users, and annual billing is 30% off. An email found costs 1 credit and a verification 0.5. Monthly credits reset with no rollover. Hunter states GDPR and CCPA and hosts on Google Cloud in Belgium. For a deeper look, see our Hunter alternatives guide.

Pros Cons
Unlimited users on every plan Monthly credits don't roll over
0.5-credit verifications Email-centred, not a phone tool
Free plan for light use No SOC 2 or ISO claim on its security page

Best for: marketers and sellers who start from a list of companies.

Not ideal for: recruiters working from LinkedIn profiles.

8. Snov.io: flat plans with outreach built in

Snov.io bundles email finding, verification and drip campaigns on flat account plans with unlimited team seats.

Plan Monthly billing Annual (per month) Credits
Trial $0, never expires n/a 50 credits, 100 recipients
Starter $39 $29.25 1,000
Pro S $99 $74.25 5,000
Pro M $189 $141.75 20,000
Pro L $369 $276.75 50,000
Ultra $738 $553.50 100,000

Source: Snov.io pricing. Annual billing is 25% off. One credit covers one prospect, one email search or one verification. Unused credits expire after 30 days but roll over on annual plans or with plan renewal enabled. LinkedIn automation slots are $69 a month each. The vendor's pages contradict each other on database size, claiming 500M+ verified contacts in one place and over 50 million leads in the FAQ, so run your own sample. It states GDPR and CCPA compliance.

Pros Cons
Unlimited seats on flat plans Database size claims conflict
Finder, verifier and drips in one 30-day credit expiry on monthly plans
Trial plan that doesn't expire LinkedIn automation costs extra

Best for: small teams that want finding and outreach together.

Not ideal for: phone-first prospecting.

9. Seamless.AI: volume prospecting on request pricing

Seamless.AI pitches itself as a real-time search engine rather than a database, and publishes no database size. Pricing is on request, quoted by contacts per month, with unlimited users and volume discounts. The free plan is up to 50 credits, and an invalid email refunds the credit automatically.

Item What Seamless.AI states
Free Up to 50 credits
Paid Pricing on request, by contacts per month
Seats Unlimited users
Credit refunds Invalid email credit returned automatically
Compliance GDPR, CCPA, SOC 2 Type II, ISO

Source: Seamless.AI and its homepage. Third-party sites quote tiers (Free, Pro, Enterprise) but no credible price range, so ask for a quote and a refund policy in writing.

Pros Cons
Automatic credit back on invalid email No published price
Unlimited users No database size to evaluate
Free 50-credit start Quote required to compare

Best for: high-volume SDR teams ready to negotiate.

Not ideal for: recruiters who need transparent pricing.

10. Cognism: the compliance-first option

Cognism is the pick when the buying committee includes legal. It's also the owner of Kaspr, so if you're comparing the two, you're looking at the same parent company. It publishes no total record count, claims phone-verified mobiles with "up to 3x higher connect rates" and Director+ data refreshed every 30 days.

Item What Cognism states
Plans Standard and Pro
Pricing On request, seat-based with 5 seats included
Credits 1 credit = 1 revealed contact; re-viewing is free
Trial No free trial stated; demo and free data sample
Compliance GDPR, CCPA, do-not-call screening (UK TPS and CTPS, US, and several EU countries), ISO 27001, ISO 27701, SOC 2 Type II

Source: Cognism pricing and compliance page. Reported figures, citing Vendr, are roughly $15,000 for the platform plus about $1,500 per user per year on Standard, and about $25,000 plus $2,500 per user on Pro. Source: Amplemarket. Treat these as reported ranges, not a quote. We go deeper in the Cognism alternatives guide.

Pros Cons
DNC screening across multiple countries Platform fee puts it out of small-team range
Re-viewing a contact costs nothing No free trial
Strong GDPR positioning Sales-led, not a recruiter sidebar

Best for: EMEA sales teams of 10 to 100 that need a defensible data trail.

Not ideal for: solo recruiters or small budgets.

11. ZoomInfo: the enterprise standard

ZoomInfo is the heavy option. It claims 500M+ professional profiles, 135M+ direct dials, 96% email deliverability and 87% mobile number accuracy, with SOC 2 Type II, ISO 27001, ISO 27701, GDPR and CCPA badges. Pricing is on request, based on features, licenses and credit usage, where 1 credit is 1 export of a contact or company profile.

Item What ZoomInfo states
Sales editions Professional, Copilot Advanced, Copilot Enterprise
Marketing editions Demand, ABM Lite, ABM Enterprise
Price On request; payment terms negotiated
Free option ZoomInfo Lite, business email required, monthly credit allowance
Reported spend Median $33,500 a year, range $7,247 to $156,032 (reported)

Source: ZoomInfo pricing and Vendr. ZoomInfo Lite isn't for current or past premium subscribers, and credits don't roll over. For a full breakdown, see ZoomInfo alternatives.

Pros Cons
Largest stated direct-dial dataset Annual contracts, negotiated pricing
Intent topics and platform depth Overkill for a recruiter
Free Lite entry point Credits don't roll over

Best for: 50+ person revenue teams that need one system of record.

Not ideal for: small teams replacing a $49 tool.

12. FullEnrich: waterfall coverage for personal and work emails

FullEnrich isn't a LinkedIn sidebar. It runs your list through 25+ sources and returns what it finds. It claims an average find rate near 80% and says it stores no contact database of its own. That's a different bet than ContactOut's, and it's useful when one source keeps missing.

FullEnrich Waterfall Enrichment: Three large cream source pitchers stand at stepped heights pouring a sparse sequence of blank record slips into one contact sleeve below.

Plan Monthly billing Annual billing
Free trial $0, 50 credits n/a
Pro, 500 credits $29 n/a
Pro, 2,000 credits $104 n/a
Pro, 10,000 credits $499 n/a
Pro, 6,000 credits/yr n/a $26/mo ($312/yr)
Pro, 12,000 credits/yr n/a $49/mo ($588/yr)

Source: FullEnrich pricing. A work email costs 1 credit, a personal email 3, a mobile 10, and you're charged only for results that are found and verified. Credits roll over 3 months on monthly plans and 12 on annual. Every plan has unlimited users. FullEnrich states GDPR, CCPA and SOC 2 Type II.

Pros Cons
Personal email at 3 credits No browser sidebar workflow
Unlimited users, rollover Mobile costs 10 credits
Pay only for verified finds Needs a list or CRM as input

Best for: recruiters and RevOps teams enriching lists in bulk.

Not ideal for: one-off lookups while browsing LinkedIn.

Snov.io Starter $39/mo Starter $29.25/mo
FullEnrich $29/mo (500 credits) $26/mo ($312/yr, 6,000 credits/yr)

Annual billing is the cheaper path everywhere, but read what you're locking in. Several annual plans hand you the full year of credits upfront, which means an unused balance doesn't carry over unless the vendor says so.

Data Accuracy and Verification: What Vendors Claim

Every vendor claims high accuracy and none of the numbers are comparable, because each measures something different (email deliverability, match rate, or phone connect rate). Treat them as marketing until you test.

How to Test Contact-Finder Accuracy: A large cream reference contact file is laid beneath a comparison loupe, with one returned envelope and one empty field window beside it.

Vendor Claim What it measures
ContactOut 99% accuracy, "triple verified" emails Ask how it is measured
Lusha 98% email, 85% US and 86% global phone accuracy Vendor-defined
Apollo 98% email accuracy Vendor-defined
RocketReach 98% accuracy; 90 to 98% deliverability on verified emails Vendor-defined
LeadIQ 85% global mobile match, phone accuracy above 90% Match and accuracy
ZoomInfo 96% email deliverability, 87% mobile number accuracy Vendor-defined
FullEnrich About 80% average find rate Find rate, not accuracy
SignalHire, Kaspr, Seamless.AI No accuracy percentage n/a

A fair pilot takes an afternoon. Pull 100 contacts you already know are current, run them through each shortlisted tool, send a small test campaign and count bounces. Gmail's sender rules expect spam rates below 0.30% for bulk senders, so a bad list does damage beyond one campaign. Our email finder roundup goes deeper on verification, and data enrichment tools covers keeping records fresh after you buy.

Credit Models: Four Ways You'll Get Charged

Model How it works Examples here Watch for
Export-capped "unlimited" Unlimited reveals inside a monthly fair-use ceiling ContactOut, SignalHire, Kaspr, RocketReach annual The ceiling in the terms, not the marketing
Per-credit, pay on hit A credit is spent only if data is found SignalHire, RocketReach, FullEnrich Different price per data type
Plan allowance with rollover Monthly credits, some carry over Lusha, Kaspr, Hunter (annual upfront) Annual credits that reset
Quote-based platform Seats plus credits, negotiated Cognism, ZoomInfo, Seamless.AI Minimum commitments

ContactOut and several alternatives work from LinkedIn profiles, so the rules matter. This is information to take to counsel, not legal advice.

LinkedIn's own rules

LinkedIn's User Agreement says in section 8.2 that members may not "develop, support or use software, devices, scripts, robots or any other means or processes (such as crawlers, browser plugins and add-ons or any other technology) to scrape or copy the Services, including profiles and other data from the Services." It also bars using bots or other unauthorized automated methods to access the Services. Whether and how a given extension complies is between the vendor and LinkedIn, and a vendor selling a tool isn't the same as LinkedIn permitting it. The practical risk for you is to the LinkedIn account you use, so keep reveals manual and don't build a pipeline on one profile you can't afford to lose.

GDPR and the Kaspr decision

The EDPB's summary says the French regulator found Kaspr's Chrome extension let customers pull contact details of people whose LinkedIn profiles they visited, from a database of about 160 million contacts. It cited breaches of lawful basis (Article 6), retention (Article 5), information duties (Articles 12 and 14) and access (Article 15), and fined Kaspr EUR 240,000. Personal emails, which ContactOut and FullEnrich both sell, raise the bar further, because a private address isn't a role-based work address.

Before you buy any finder, ask four questions: what the vendor's lawful basis is, how people are notified, how long records are kept, and how objection and access requests are handled.

CCPA and PDPA

California's CCPA gives residents rights to know, delete and opt out of the sale or sharing of personal information. In Southeast Asia, Singapore's PDPA governs how organisations collect, use and disclose personal data, and neighbours such as Malaysia and Indonesia run their own regimes. Ask each vendor which regions its data covers and whether it can exclude yours. ContactOut's US and UK exclusion option and Cognism's registered California data broker status are two examples of region and registration controls.

In the US, FTC rules carry civil penalties of up to $53,088 per violation, and the Do Not Call registry rule doesn't apply to business-to-business calls, though a revealed mobile number may be personal. Under the TCPA, individuals can recover $500 per violation, which courts can treble for willful violations. In the UK, TPS and CTPS cover businesses too, and the ICO fined one company £160,000 in May 2026 over calls to registered numbers.
